My poor old man suffers with arthritis. He is taking a quarter of Pardale twice a day, prescription from the vets, plus YuMove and turmeric from Dorwest daily. Is there anything else I can give him? He's doing ok, actually better now he is taking turmeric. A friend has suggested cod liver oil. Would that help too? He's had a bit of a bad week and I've just accidently hurt him moving his leg. The vets haven't suggested anything other than pain relief, I think because of his age.
